Barium fluoride windows can be used up to 800 c in a dry environment but prolonged exposure to moisture can degrade transmission in the vacuum ultraviolet range.

Barium fluoride baf is a crystalline compound of barium and fluoride used in optical applications in the nir vis and mwir spectrums.
Barium fluoride baf2 is the fastest known scintillator material and barium fluoride windows and plates are used in vuv and infrared spectroscopy.
Barium fluoride is resistant to high energy radiation performing well in dry temperatures up to 800 c but transmission in the vacuum uv vuv degrades over time in a moist atmosphere and the material is susceptible to water corrosion at 500 c.
Barium fluoride baf2 shows good optical transmission over wide spectrum range which can be used as uv ir windows in 0 15μm 12 5μm.

The material can be used up to 800 c but can be subject to reduced.
Baf 2 is recommended for use as a vacuum ultraviolet window where high radiation resistance is required.
Baf2 is a fairly hard material but is very sensitive to thermal shock.

For an equivalent thickness the transmission extends approximately 1 micron further into the ir than calcium fluoride.
While barium fluoride windows are less resistant to water than calcium fluoride baf 2 windows are the most resistant optical fluoride to high energy radiation but feature lower uv.
Baf2 has excellent transmission from 200nm 12μm and resistance to high energy radiation.
Barium fluoride is used for optical windows prisms and lenses transmitting from ultraviolet into infrared it can be used as an infrared laser window or lens.
Although these windows are ar coated on both sides for ir use barium fluoride is commonly chosen for applications that.
Barium fluoride is often suitable for applications in the passive ir band 8 to 14 μm and is often used as a viewport window for thermal imaging inspection application in electric power facilities and petroleum indutries.
